OMAHA, Neb. (AP) — Authorities say a man wearing only boxer shorts stole a pickup and drove it into a Southwest Airlines plane at an airport in Omaha, Nebraska, causing minor injuries to three people on board.

Eppley Airfield Police Chief Tim Conahan says an officer spotted the man outside the terminal Thursday evening, screaming that people were trying to kill him. When officers approached, the man ran, climbed a fence into the gate area, undressed and stole an airline pickup.

The man is in custody. His name hasn’t been released.

Southwest spokesman Chris Mainz said Friday that the plane’s nose gear tires were flattened, so another plane flew the 113 passengers to Denver, landing three hours later than originally scheduled.
